SANITARY TELEPtIONE-MOUTHPIECE.

Specification of Letters Patent.

Patented Feb. 4, 1913.

Application filed May 8, 1912. Serial No. 695,810.

To all whom it may concern Be it known that I, JOHN MCCAUSLAND,

' a citizen of theUnited States, residing at the city of Providence, inthe-county of Providence and State of Rhode Island,.have inventedcertain new and useful Improvements in Sanitary Telephone-Mouthpieces,of which the following is a specification, reference being had thereinto the accompanying drawing. This invention relates to a sanitaryreadily'detachable transmitter mouthpiece, and has for its object toprovide a telephone transmitter coneshaped mouthpiece made of paper orother readily destructihle material to be readily removed from thetransmitter casing and destroyed after using to be replaced by a freshone.

A further object'is to provide a wire bracket or yoke to be readilyattached to any transmitter casing, said"bracket being adapted toreadilydetachably support a transmitter mouthpiece so that mouthpiece cones maybe provided of such inexpensive material and construction that they maybe removed and destroyed after each person has used the telephone toprevent the spread of contagious diseases through a continued use of asingle mouthpiece.

Vith these andother objects in view, the invention consists of certainnovel features of construction, as will be more fully described andparticularly pointed out in the appended claims.

Of the accompanying drawings: Figure 1 is a side elevation showing myimproved device attached to a telephone transmitter casing. Fig. 2 is adetail in perspectiveshowing the diaphragm protecting plug. Fig. 3, is adetail in perspective illustrating my improved cone-supporting bracket.Fig. 4 is a detail in perspective of my improved paper mouthpiece cone.Fig. 5 is a modification showing a clip or clamp for releasably securingthe cone to the protector plug. Fig. 6 is another modificat-ion showingan internally screw-threaded collar into which the cone may be removablysecured. I

Referring to the drawing, 1 designates the ordinary transmitter box orcasing, and 2 the diaphragm protector plug which has a threaded bodyportion 3 adapted to be screwed into the front plate of said casing- Myimproved cone-supporting bracket is preferahlv constructed of wirehaving arms i t adapted to extend up around the barrel port-ion 3 of theplug and having forwardly extending portions 5 with upwardly extendingarms 6, which arms'are bent back upon themselves forming a U-shapedslightly resilient yoke 7 for the reception of the cone-shapedmouthpiece 8. This mouthpiece, as illustrated in Figs. 1 and i.

is provided on its outer surface near its inner end with an annulargroove 9'for the reception of the yoke portion of said bracket.

One of the essential features of myimproved device is that thismouthpiece is a plain hollow truncated cone constructed of paper orfiber, or other inexpensive readily destructible material, the shapebeing such that it can be made froni paper at. so little expense thatone can afford to use a fresh cone each time the telephone is used, orparticularly after having been used by :ll\-' other person. Such adevice would heof great service particularly in public telephonestations to prevent the spread of contagious diseases, which oftenresults from the use ofa common mouthpiece permanently attached.

In applying my improved deviceto any telephone it is only necessary toremove the usual permanent mouthpiece, pass the body of the diaphragmprotecting .plug through between the arms 4 of the bracket and screw theplug into the casing thereby binding the bracket to the casing andsupporting the forwardly extending U shaped yoke portion just in frontof the plug to receive the mouthpiece. In applying the mouthpiece itselfto this yoke it is only necessary to pass the annular grooved portiondown between the arms of said yoke which securely holds the mouthpiecein proper position. from which it may be readily lifted off whendesired.

The modification illustrated, in Fig. 3 shows a clip 10 permanentlyattached to the plug 2 and having a biting jaw 11 which is adapted toengage one end of the mouthpiece to bite and secure it in position. Thatillustrated in Fig. 6 shows an internally threaded collar 12 attached tothe plug 2 into which the cone may be secured by sim-
